Maximum larval population of Helicoverpa armigera was observed in 12th (7 .36 larvae / 5 plants) and 11th (9.20 larvae / 5 plants) standard week whereas it was minimum in 47th (0.20 larvae / 5 plants) and 1st (0.12 larvae / 5 plants) standard week, respectively whereas highest population of Exelastis atomosa was observed in 11th and 10th SW and lowest population was observed in 6th & 15th and 4th SW, respectively during both the year. Clavigralla gibbosa population attained the peak during 7th and 8th SW and minimum population was observed during 16th and 2nd & 16th SW and the peak larval population of Lampides boeticus was recorded in 10th SW during both the years. The lowest population was observed in 14th and 15th SW during 2018-19 and 2019-20, respectively. The peak period of occurrence of M. obtusa maggot and pupae was observed in 9th & 12th SW and 11th & 12th SW during both the year, respectively. The correlation coefficients between the incidence of Helicoverpa armigera, Exelastis atomosa, Clavigralla gibbosa, Lampides boeticus and maggot of M. obtusa with abiotic factors showed both positive as well as negative relationships at non significant level during both the years. The correlation coefficients between the pupae of M. obtusa and weather factors had significant positive correlation with minimum temperature (0.621* & 0.716*), maximum temperature (0.588* & 0.516*) and sunshine hour (0.600* & 0.561*) while relative humidity showed significant negative correlation (-0.681* & -0.646*) and rainfall had non significant negative correlation in both the years, respectively. During Kharif, 2018-19 the Torymoides spp. and Ormyrus orientalis spp. was recovered for the first time from the pods collected on second fortnight of February and the level of parasitization was 14.28 per cent. The parasitization increased on first fortnight of March and reached to its maximum level 25.71 per cent. During Kharif, 2019-20, the maximum parasitization on first fortnight of March and reached to its maximum level 25.00 per cent. Out of 30 germplasm of pigeonpea evaluated against Melanagromyza obtuse, only three germplasms viz. ICP 8863A, ICP 6443 and JBT 46-61 were found moderate resistant against pigeonpea pod fly. None of the germplasm fell under highly resistant category during both the years of study. All the treatments were significantly superior over the control when observations on per cent pod damage were taken at 3, 7, 10 and 14 days after treatment. Chlorantraniliprole 18.5 SC @ 30 g a.i./ha was found best in reducing pod damage caused by Melanagromyza obtuse. Emamectin benzoate 5 SG @ 11 g a.i./ha was the second best treatment in both the year. The maximum cost benefit ratio of 1:14.56 was obtained from the plots treated with Chlorantraniliprole 18.5 SC @ 30 g a.i./ha followed by Emamectin benzoate 5 SG @11 g a.i. /ha (1:13.62). The minimum (C:B) ratio of (1: 5.81) was obtained Imidacloprid 17.8 SL @ 20 g a.i./ha treated plots.ThesisItem Open Access Quantification of insect-pest diversity and management of Earias vittella (Fab.) in okra, Abelmoschus esculentus (L.) Moench(ANDUAT,Kumarganj, Ayodhya, 2020-10) Kumar, Suraj; Kumar, PankajThe present investigation entitled “Quantification of insect pest diversity and management of Earias vittella Fab. in okra, Abelmoschus esculentus (L.) Moench” were carried out for two consecutive crop seasons i.e., kharif 2018 and 2019. A total of 19 insect pest species were recorded during the entire crop season. Among them six species were major and thirteen of minor importance. Two species of ladybird beetle, two species of spider and egg parasitoid Trichogramma chilonis was recorded as natural enemies of different okra pest. E. vittella caused dropping, drying and withering of tender shoots at vegetative stage. Maximum shoot damage of 23.20 per cent was recorded in untreated control. The natural enemies viz, ladybird beetle, predatory spider and egg parasitoid of Earias vitella observed predating upon different insect pest infesting okra crop. Correlation of major insect-pest and natural enemies with weather parameters were worked out and it is revealed that minimum temperature had positive significant correlation (r= 0.757** and 0.835**) during both the years with per cent shoot damage. Maximum temperature showed non-significant negative correlation during 2018 and significantly positive correlation during 2019 and correlation values in respective years were r= -0.138 and 0.810**, respectively. Correlation with minimum temperature and Coccinella septempunctata showed positive significant correlation (r= 0.196 and 0.329) during both the years. Out of 30 germplasm of okra evaluated against E. vittella, none was found immune from damage of E. vittella. However, damage level varied from 9.00 to 33.07 per cent in case of shoot damage and 12.52 to 36.55 per cent in case of fruit damage. Lowest shoot damage was found in HRB-55 (9.00 %) followed by EMS-8-1 (13.65%) whereas Pusa Sawani showed maximum shoot damage of 33.07% followed by Parbhani Kranti (32.74%) and GS-43 (31.57%). Based on overall mean per cent fruit damage, the damage was varied from 4.81 to 22.42 per cent.ThesisItem Open Access Germplasm screening, population dynamics and evaluation of IPM modules for the management of gram pod borer, Helicoverpa armigera (Hübner) in chickpea (Cicer arietinum L.)(ANDUAT, Kumarganj, Ayodhya, 2020-09-14) Sharma, Sanjeev; Chandra, UmeshThe present investigations entitled “Germplasm screening, population dynamics and evaluation of IPM modules for the management of gram pod borer, Helicoverpa armigera (Hübner) in chickpea (Cicer arietinum L.)” revealed that the larval population H. armigera (Hub.) recorded at 50 per cent flowering stage, 50 per cent pod filling stage and mean per cent damage at maturity stage at weekly interval on 10 randomly selected plants starting with 50 per cent flowering stage, 50 per cent pod filling stage and maturity stage ranged 2.90 to 8.30, 3.10 to 9.40 larvae/ 10 plants and 12.97 damage per cent larvae to 37.12 per cent during Rabi, 2017-18 and 3.33 to 8.00, 3.80 to 10.20 larvae/ 10 plants and 13.25 damage per cent to 36.48 per cent during Rabi, 2018-19 respectively.
